LOSS OF POWER

Electronic diagnosis has identified faults with the two fuel sensors on my VW FSI 1.4 -2004. These have been replaced --but I am still experiencing serious intermittent loss of engine power.
Any ideas?

    Intermitent Loss of Power on VW FSI 1.4 - 2004.

    This has happened several times on my 2004 Golf. It seems to occur when pulling away and after a gear change. Suddnely all acceleration disappears and no matter how much I press on the accelerator there is no power and the car slows. The last time this happened I tried to pull over but suddenly the power returned and I could accelerate again.

    No warning lights are coming on and my garage has replaced the nox sensor and tested.

    I have the same problem on my 1.6 FSI Golf. The garage so far has replaced the fuel pump, pressure switch and the ECU has been reprogrammed by VW. So far its cost me over £400 and the problem is still there

    My wife is currently experiencing the same problem in her 04 plate Golf 1.6fsi. The car randomly decides to loose power but no lights come on the dash, it doesn't stall, the steering doesn't go and it doesn't stutter. It just feels like you have no acceleration even with the acc pedal pushed all the way down. Its like something is blocked and you cannot get any more power then it suddenly clears and you get acceleration again. Very dangerous at juctions or on the motorway but VW just offer a computer diagnosis for £80 that they have already told us will not show anything because the engine light hasn't come on and so nothing will be logged.



    Can anyone help?? Apparently its relay 109 on the TDi range (£10) but cannot find a fix like this for petrol 1.6fsi.



    Sounds expensive - Help!

    My VW Polo TDI kept losing power and I had to keep my foot on the accelerator to keep the car going.

    The garage replaced one of the injectors and the car is perfect now.

Number of things
1 fuel injectors
2 worn throttle body
3 inside gas tank sending unit filter needs replaced
4 a/c compressor failing
5 replace air filter
6 depending on mileage of vehicle worn cam, bearings oil rings
7 oil and water mixing together (oil will look like chocolate milk on dipstick if this happens
8 not enough air from the electric fan in front of vehicle (hook constant power and a switch with power key off)
9 wrong fuel type (maybe you car requires premium)
10 alternator wareing out and makeing a slow drop in power
11 binding brakes or emergency brake line binding
12 worn sparks plugs wires and electrical unit that houses this
13 worn capacitor looks like a little tear can with power points on it

this is just basic diagnosing without being there to see the vehicle in person these are the things right off the top of my head that i can help diagnose right now
some of these things wont show on a diagnostic cause there more mechanical and sensors wear with mechanical
hope this helped you in your quest

I have a Golf 1.6 FSI 2004 model. I have just had problems where I was losing power when driving on an incline. When going up something steeper, my speed reduced to around 20mph and I was being overtaken by lorries! to cut a very long story short, after telling VW that I suspected it was exhaust problems, (having experienced such problems on previous vehicles in the past) it took them various diagnostics and referrals back to VW, for the garage to confirm it was infact a problem with the exhaust. It cost me £1300 for them to confirm what I said some months ago what I thought the problem was. It was a case of 'the computer says no'! Because the problem could not be picked up on diagnostics, there was 'nothing wrong with the vehicle'. My advice to anyone after my dealings with 'VW Customer Care', is to say that they don't care at all. As soon as I can be rid of my car...I will, and it will never again be a VW.

Think Safty first. Have you had the car's codes checked first? Check the air intake tube for leaks and all vacuum hoses. For the intake you might hear a hissing noise. For the vacuum hoses check for dry rot, cracks. With a little soapy water you can spray them if the idle gets better or worse replace that vacuum hose.

Your EVAP purge valve may be faulty. Also, check the vaccum lines attached to the valve for any signs of wear and tear. Should be located next to the coolant tank.

Hi there,

Firstly, I must ask: did you take your vehicle to a VW dealership? Did you witness this mechanic connect a scanner to your vehicle's computer to extract any Fault codes? Can you confirm he correctly diagnosed a faulty fuel pump?

Your vehicle is EOBDII compliant, therefore all electronic faults will be immediately stored in the computer and will just require a 15min process to read these codes.

By doing this, you will be able to correctly diagnose the fault and rectify the problem quickly (both fuel pump & speed sensor faults can be quickly identified in this manner).

If you did not take to a VW dealership, then only a garage equipped with the proper EOBD-II (European On-Board Diagnostics V2) scanning tool will be able to communicate with your vehicle's computer.

If in doubt, you should ask to see the code readout for yourself.

If you wish, you can post your codes on here - we will be happy to confirm what the codes mean.

Vw golf se fsi 2006 30,000 miles. exhaust warning light on


If it is the 1.6 FSI model, it is very sensitive to the type of gasoline, it should be octane 97 or higher.
Very commonly, owners of this model use the 95 Octane gasoline, which seems to work ok, but the sensors in the exhaust (yellow motorwarning light) will eventually (can take a few years) clog up and you cant clean it or change the sensor easy either as you need to remove the whole exhaust system.

So either you let VW fix this for you (expensive) or you do it yourself (need a decent garage, equipment and a new sensor).

The Nox sensor fits after the catalyst (non FSi models had a rear lambda) the lambda on your car is near the engine and has 5 wires because it is a broardband type.
