There are 4 coils, one for each cylinder. Audi tend to replace one at a time to save costs. So yes this is probably quite likely.

Hi Audi A4 1.8 T sport, X reg failed mot on high emissions Front Lambda replaced, and readings still high (running rich) any ideas please


hi this could be a few things but more than likely it is either the MAF sensor or MAP sensor, these things do roughly the same thing, but the MAP also adjusts the timing through the ECM , either one would cause this to "over fuel" and not burn correctly, the starting place would be try the MAF first as this is the common one, make sure spark plugs have been changed as this also will help, if you still get a fail, then try the MAP sensor...hope this helps good luck..

2004 Audi A4 misfire


it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

Audi 1.8T sport Auto (2001) heavy smoke and engine buring smell


The engine could be shot, oil is being burnt off by the actions of being sucked into the bores via worn piston rings then ejected out of the exhaust

If you sent the car in for an MOT and a Service I would ask the garage what they did to it as the car would have failed on its emissions test if that much oil was coming out .

It could have been a fault on the oil pump or lack of oil in the first instance and maybe an overfill on the service

You paid your money now go back for redress

Mot failure emmisions


Internal oil leak, change the spark plugs and cables, oil, filter and add Lucas oil. Take the car for inspection and let me know how it goes. For the belt depends where you get the parts and who does the work.

Lambda probe fault possibly


I bought a 2000 polo 1.4 yesterday after having an MOT. The warning lamp came on today but the car is running fine. Whether its the Lambda sensor or just the light itself is a common fault, I think garages turn off the lights to get it through the MOT then they come on again in a day or two!
