53

very top

only space for 1 relay which is missing
only space for one fuse also missing

i go the same mate at top is spare relay and fuse holder what thye do?

coolant temp guage why the hell would it need a relay?

Sorry to gatecrash your topic, but I have a question which follows on.

I have a 1991 gti cabriolet which I believe, after reading the various other threads on this site, needs a new fuel pump relay.  Fuel pump is beginning to be tempremental but works after the relay is taken out, cleaned and replaced.

My question is, which number relay do I need (I can't seem to find anything in the Haynes manual) and where is the best place to source them from?

Cheers

Simon

The top position which on your car is empty is where the water temp control unit goes . It looks like a relay but is not , original parts have number 43 on the top. Only know this as have just sorted problem on my temp gauge by fitting replacement unit.
