How to remove right motor mount

have a compression test done to check for head gasket or cracks.. Check coolant level in the radiator not the reservoir. Have a cooling system pressure test done to check for leaks. Have a flow test done on the radiator to check for blocked cores. Have the fault codes read to check for sensor/ servo failure.

is it an automatic or stick? there are switches and relays that the signal must pass through before you get to crank from the key

yes this is an easy fix. just open your hood, search for the fuse/relay box, then replace main engine relay.

Hi if your car runs fine from cold and starts fine when cold, but then if it starts playing up when it gets to near running normal temp then this is a good indication that the oxygen sensor is up the shoot and will need replacing.
the reason it points towards this being the fault is that the oxygen sensor only starts to work when it reaches a certain temp so if your car runs fine when cold but plays up when hot or warm then the chances are getting the oxygen sensor (or lambda sensor for its proper name) changed should then solve your problem.

let me know how you get on or if you need further assistance ok

Thanks for the solution on that Good job.

This vw has two fuel pumps one low pressure pump in tank and one high pressure pump under car make sure both are getting power and both are pumping, next try switching out the coolant temp sensor for the computer. The old vw cis fuel injection systems are very complex, so if you don't know what it is don't touch it get a book or better on old vw mechanic! ; )

search for the IGNITION FUSE inside your fuse box, located below your dashboard. replace the fuse (make sure to use the recommended fuse rating).
