Hi All

Would someone know how to fix this problem or advice me what to do, I have Audi A3 8v 13 plate, the coil light comes on and the engine management light. the car shakes at 25 in 2nd and 35 in 3 and 45 in 4th, the coil light and engine light comes on when I start the car, ive had the Air flow mass meter changed and the boost pressure valve and sensor and the wiring and it still shaking, could you please advice?

 

Thanks

Any errors?

the engine management light comes on and the coil light comes on when I start the car, it feels really slow then is fine and goes fine but that happens often, the car shakes in every gear while I am driving not under load or braking. I am trying to avoid going to Audi as it would be expensive, would anyone have any ideas?

If the EML comes on it should hopefully have stored some error codes. VCDS will read them (there may be someone on here in your area that has it) or a cheap ODB2 reader may show some if not all of them. You need the codes to start narrowing down what the issue is.

What I’m not certain about here Stuart is whether the EML (and glow plug coil - it is diesel??) comes on as they should before you start it, but goes out when it starts - as it should - i.e. all is well in that department. Sorry but I’m not understanding your description. 

It would appear that your vibration is occurring at a certain rev. point ( different speeds in different gears). Could you confirm what actual revs. this problems shows up? 

Audi dealer? Have you tried an independent in your area, or better still - if it is indeed a diesel - a trusted local diesel specialist. Neither should charge you much to give an opinion on the problem. 

Perhaps you could fill in the detail for us.

Kind regards,

Gareth.
