Main relay symptoms

[Doc308]

I've noticed in a lot of threads that a defective main relay is often implicated in the production of quite a few different symptoms in these cars.

Would someone be so kind as too provide for a reference list of the symptoms which could occur when the main relay malfunctions ?

Thanks.

Car won't start.

Also sometimes, I recall, mine would start, but the TCS light would remain on due to the power not coming up right to the computer apparently.

When it won't start, you can usually confirm the problem by hitting the upper rear panel behind the passenger's seat and it will hopefully start.

If you have a doubt about the main relay, take it out and have someone resolder all the connections on the board and the symptoms should go away.
