Question about 1986 Audi 5000 CS

1 Answer

Tacho drops off when driving, comes back on sometimes Petrol 3000

I seem to have an intermittent fault with the tachometer on my 3000 V6 Petrol Mitsubishi Shogun. Where is the signal generated? Is there a ribbon cable in the clock housing etc? Is this a common problem?

It is not a common problem, and the cause of these kinds of issues is the small circuit board that sends the signal to the tach needle stepper motor or the stepper motor itself, a stepper motor is a motor that can rotate itself to an infinite number of positions and hold that reading or setting. The cure is to pull the tach out and send it to a Mitsubishi factory authorized repair facility, they are the only ones who have parts and manuals.

My Sonoma 4.3 v6 is having some issues the rpm gauge is jumping at any giving time besides idling would you know why and I couldn't run dynastics


tachos get their signal from the coil or the ignition control module or ECM
check for ;loose / broken wires in the harness or at connections
There will be no fault codes for tachs unless it affects an adjacent sensor
could be a faulty tacho unit (tacho--tachometer--rev gauge --rpm indicator )

How do i wire a tachometer into a 2000 daewoo lanos?


I suggest an Auto Electrician....... but you CAN do this.... BASICALLY it is a wire running from the Power Scource.... Ignition Switch,.... to the Tacho, then from Tacho to Distributor if it is a Petrol Vehicle, but a DIESEL is completely different..... THAT needs a Vacuum operated Tacho via the Injector Pump and I STRONGLY Recommend a Electrician for that..... Pain in the *** to fit to a Diesel.... I HAVE A diesel.....

I have a 98 model petrol v6 dualcab auto and tacho has stopped working . how do i fix it ?


Easy really you recycle it for a nice little peugeot partner diesel van or a VW equivilent and get 70+mpg ,but if if you insist on driving this gas burner CO2 production machine then to repair this fault you most likely need a new tacho ,the feed is taken from the ECU supply to coil pack so you will need to take the dash out and then look on the printed circuit on the back and check for a feed as sometime the plastic printed circuit breaks with vibration but on a vehicle this age i would expect the dial has failed but i could be wrong .

1994 Nissan KingCab automatic the OBD lights comes on inermittently, the tachometer is stuck, the odometer works intermittently - have less than 100K miles, the passenger lockset don't work, = Where can I...


If you bought it from a car yard,take it back to get repairs.The speedo fault may be from the speed sensor head on the gearbox which will in turn set off the OBD light.It seemed to be a common problem in that year for the tacho fault.Both speedo and tacho fault can be in the instrument panel.So it may need to be tested anyway before replacing parts and wasting $$.Try squirting some powdered graphite into the lock and rattling the key and pushing it in and out.Locks that aren't used much can freeze up.You can use WD-40 but graphite lasts longer.and is preferable for all locks.
I Cant help you with specific places to go due to different country but try car dismantlers or google for places in your area.Most states,cities have there business phone books online also.
I hope this helps you with the problems and minimises your spending.
