SOURCE: sevice abs light code 63 91' vette

So is your ABS light on? Computer won't hold a code for the ABS light. There's 4 sensors one at the back of each wheel one of them is bad. As longs as your brakes are working normally you can at your time to fix it. ABS was made for panic stops only thats why the pedal pumps fast when you stop hard.

SOURCE: p0471 and p2002 codes, Audi A6 2.0 DPF S-Line Auto

A6 2.0 TDI 1997
Got same problem around 35000Km. Engine light on with same error P0471. I was in France, Audi reset error and found nothing suspect. 4 weeks later same problem. (I felt engine was executing filter regeneration cycle very often). After 1 more week, Exhaust symbol came into large display and engine into safe mode (max 90Km/h). Contacted my Audi dealer in Belgium. They immediately told me pressure sensor (measures obstruction over DPF) was defective ; happens more often. Car was just beyond 2 Y old. Replaced under warranty. No more problems.

What is the exact code you got when you scanned the computer?

It sounds like you need a new Diesel Particulate Filter.

I have Lexus gs450h 2010 with trouble code c1555 and steering wheel is hard to turn I already replaced steering ecu after calibrating work fine but for only 20 minutes and was unable to clear the same code...

The ECU wasn't bad. The power steering unit is. The ECU compensated for the bad unit, until it wouldn't take it anymore. Replace the steering unit under the dash. Just a note though. I would do a wiring diagnostic first, to make sure all the wires are good.

Take car to AutoZone and use free Diagnostic Code Reader to identify exactly were problem using code. Remember it isn't always the diesel particulate filter (or DPF). Fault normally is do to soot from diesel gas clogging the filter. If it were me I would have tune-up done every 4 years and have all filters (except Oil filter) taken out and blown every month to keep sensor from tripping.

Error code 55 on vauxhall meriva whats it mean

Error 55 is Diesel Particulate Filters (DPF)
Reducing diesel soot emissions by 80%

If you're buying a new car and plan to use it mainly for town-based, stop/start driving it would be wise to avoid a diesel car fitted with a Diesel Particulate Filter (DPF) because of the possible hassle of incomplete 'DPF regeneration'.

The exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems - AA patrols are regularly called to cars with the particulate filter warning light on indicating a partial blockage of the filter.

Even if your driving isn't mainly urban/stop-start, changes to driving style may be required to get maximum benefit from these systems.

How do they work?
Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

As with any filter (think of the bag in your vacuum cleaner) they have to be emptied regularly to maintain performance. For a DPF this process is called 'regeneration' - the collected soot is burnt off at high temperature to leave only a tiny ash residue.

Regeneration may be either passive or active.

Passive regeneration
Passive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don't get this sort of use car manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process.

Active regeneration
When the soot loading in the filter reaches a set limit (about 45%) the ECU can make small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration. If the journey is a bit stop/start the regeneration may not complete and the warning light will come on to show that the filter is partially blocked.

It should be possible to start a complete regeneration and clear the warning light by driving for 10 minutes or so at speeds greater than 40mph.

If you ignore the warning light and keep driving in a relatively slow, stop/start pattern soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will have to take the car to a dealer for regeneration.

Expensive repairs
If you continue to ignore warnings and soot loading keeps increasing then the most likely outcome will be that you will have to get a new DPF costing around £1000.

DPF additives
The most commonly fitted type of DPF has an integrated oxidising catalytic converter and is located very close to the engine where exhaust gases will still be hot. This heat means that passive regeneration is possible.

There's not always space close to the engine though so some manufacturers use a different type of DPF which uses a fuel additive to lower the ignition temperature of the soot particles so that the DPF can be located further from the engine.

The additive is stored in a separate tank and is automatically mixed with the fuel whenever you fill up. Only very small quantities are used though so a litre of additive should treat around 2800 litres of fuel - enough to cover 25,000 miles at 40mpg.

You will have to pay to get the additive tank refilled at some time in the car's life, and we've heard reports of dealers charging up to £200 to re-fill a half empty tank.

AA experience
We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways.

On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases.

With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed.

There's no evidence in AA breakdown data that the problem's going away - newer car models seem just as likely to sufffer DPF problems if not driven 'correctly' as those built when DPF's were introduced.

Check the handbook
If you buy a car with a DPF fitted it's important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life.

I have seat Ibiza 1.6 tdi year 2010 which has flashing glow plug light on dashboard

if your vehicle is fitted with a diesel particulate filter which is not to be confused with an ordinary catalytic convertor it will need to have what is known as a regeneration on a motorway or dual carriageway in third or fourth gear drive at a constant speed of 50-80 kph keeping your rpm between 2350-3000 for approx. ten to fifteen minutes this tells the ecu to pre inject fuel and post inject fuel to make your exhaust gases hotter to burn out all the deposits in your diesel particulate filter if you don't have a dpf
you may need a new catalytic convertor
or you can buy a solution that you add to your fuel to clean them out but find out if you have a dpf first because if you don't you need the solution for cleaner emissions if you do you need the solution for your dpf to burn hotter
hope this helps

How do i clear a codes in a loop on my ECU

If these fault codes have become embedded even after an ecu reflash and software upgrade, why does it worry you?
Unless the mil light stays on all the time.
Surely these codes will only be read when a diagnostic test is carried out?

I keep hearing that I need to find and pull fuse 14 on my 96 subaru legacy 2.2L to try and reset the AT Oil Temp light that is flashing at start-up. The lid is missing, so I have no idea where this fuse...

Yes that is right:

Current trouble codes shown on the display are cleared by turning the ignition switch OFF after conducting self-diagnosis operation. Previous trouble codes, however, cannot be cleared since they are stored in the ECU memory which is operating on the back-up power supply. These trouble codes can be cleared by removing fuse 14 (located under the right lower portion of the instrument panel).

  • The No. 14 fuse is located in the line to the memory back-up power supply of the TCU and ECU (MPFI). Removal of this fuse clears the previous trouble codes stored in the TCU and ECU (MPFI) memory.
  • Be sure to remove the No. 14 fuse for at least the specified length of time. Otherwise, trouble codes may not be cleared.
When the Engine Control Module (ECM) , battery terminals, etc. are disconnected after memory is cleared, idling speed may increase. This is not considered a problem because the ISC Valve duty controlled learning value has been cleared. To return the engine to idling speed, idle for approximately 2 minutes with air conditioner "OFF".

Here is fuse #14 loc in panel Now its hard to see, but they go from the top left from 1 - 7 then it repeats for the next row 8 - 14. SO 14 is 2nd row from the top last one on right side.

The DPF is designed to 'Burn off' the soot deposits that accumulate, but in order for this to happen the exhaust has to become really hot. The DPF will fill up if the vehicle does a lot of short trips and the exhaust fails to get hot. The cure is a long hard drive
