'sticky Relay - Glow Plugs' Tdi 90hp

[BrianAll]

Howdy, new member, looked in a few times but this is my first post. After 3rd RAC call-out the last patrolman said he thought I had a 'sticky relay'. It buzzes a bit when ignition switched on, sometimes. When it has broken down the glow plug light on dash didn't come on at all. Lived with this for 6 months or so and had 3rd call-out this week. Previous man said get it to your main dealer, and left me thnking I had a loose wire. Sounded like 100's of pounds of diagnostic spend so I put off going. Getting to the point: the Owners guide says Relay R12 is the one I need to replace, I've just lowered the fuse/relay cluster from the dash and am presented with 4 rows of relays (some empty slots) and lots of numbers ranging from 53 to 168. Does anyone know which one is the glow-plug relay please ? Thanks, Brian (Norwich) ;)

on mk 1 is number 36 however the replaements can have other numbers on a common one is no. 103 you may need to lower the fuse box down to access the underneath layers to find it. one for sale on ebay at moment.

Thanks Martin. Since I posted the question I have been using the search option and found a question posted in 2004 'where is the glow plug relay' and one of the replies was kind enough to show a photo of the relay. It sits at the far right of the bottom row, on layer 3. Yes, yu're right, mine is numbered 103. Thanks. I will now undo tie clips, take off layer 2 to get to layer 3 and take out the offending relay. On another post from seach I saw that the relay problems are often down to poor soldering within the relay, so I am hoping this is the case with mine, it will save me

I've had the same problem, with a Galaxy I bought on Monday. When I'd finished the test drive I turned the car off and removed the key, imagine the owners face when the engine was still running!

When this happened it helped me knock him down a bit as I thought it was just the fuel cut off solenoid. When I got it home it turned out that some cowboy mechanic had wired the solenoid to an ignition live with a scotch block, this did not solve the problem obviously! So I removed the wire and guess what.... the glow plugs would come on now and then as would the solenoid... So after some searching about on here I finally found the relay and resoldered the joints in it, and hey presto it seems to have sorted the problem, touch wood!

 

Now for a new cambelt and full service, plus a good valet!
