Good Morning, I’m new to the site and hoping you guys can help me out if possible.
Last year my a3 (2006) needed new spark plugs fitting, I was idling in a safari park, engine warning light came on, went in to limp mode etc.
My local garage replaced them, job done. This was last august.
2 weeks ago same issue, was stuck ina traffic jam for about 2 hours barely moving and the engine started shaking, engine light came on but this time flashing and wasn’t sure if there was a brief smell of sulphur.
Took it back to the garage, spark plugs again, replaced under warranty. All sorted… so I thought
The garage also took a look at a power steering issue I have the next day, when finished I left the garage and the spark plug error came back!
They took another look and this time replaced the ignition coil, all sorted…
The power steering issue they couldn’t sort because of a sensor so I took it to another garage with a good rep for a 2nd opinion. Whilst the garage were sorting this out the engine warning light came on again!
They have said they have fixed this now with new spark plugs! I told them this was the 3rd time it had happened and if its likely to be anything more sinister, they said to leave it with them. I also mentioned when I was topping up my oil the other day I noticed a yellow residue in the oil filter cap and running down the side. Does this mean the head gasket has blown? There is no coolant leaking or oil, engine temperature normal.
I’m just at a loss at what it could be,
Anyone here have any suggestions?
