Is it easy to replace your own glow plugs . I have a 02 jetta TDI and would like to save some time and money by doing it my self or should I just let the dealer do it.

I'm also a TDIClub member. Two of mine broke off in the head when I tried to chg them. Carbon builds up on the threads making removal difficult/impossible. Ideally one would remove them every 30,000 and put anti-seize on them after cleaning.

I HAVE A 2001 VW JETTA TDI. THE ENGINE LIGHT STAYS ON. I HAD IT CHECKED WITH COMPUTER AND IT HAS A CIRCUIT A OF THE GLOW PLUG CODE. ANY REMEDY'S?


After about every 100Kms one or more glow plugs burn out. Think of them like toaster elements which ignite the fuel on start.
The recommended solution is to replace all 4 at once as the labor for changing one is the same as for changing all 4.
If you change just 1 (and you would have to be able to figure out which one it is - not easy) the other 3 will follow (failing) in a few weeks afterward.

2000 Jetta TDI: How do I change spark plugs on 2000 VW jetta 2.0...


You're in the TDI (diesel) solutions section so it uses glow plugs.
If it's a petrol engine 2.0L then it would be accessible above and below intake manifold using a swivel spark plug deep socket.

hi changing glow plugs is nothing to do with this code i would change the fuel filter and put a injector cleaner into the fuel tank as if this doesn,t cure the problem the only other thing that affects the pump is the timming belt has it slipped a tooth is there a marked drop in preformance if not these pumps are expensive very expensive best of luck yates210456

02 VW engine light that stays on


You probably need to replace the glow plug harness. The contacts in the boots that connect to the glow plugs get corroded and throw off the resistance of the circuit. The controller in the VW measures whether your glow plugs are good or not by testing the resistance in the circuit. Test all the glow plugs like DickyIV1 stated and if they are all good try cleaning out the crud on the contacts in the glow plug harness. You will then either need to clear the error code or wait several trips for it to clear itself. If it never clears itself or if it comes back on after you clear it then the glow plug harness is too much of a mess. This is really common on the TDIs (mine needs to be changed but i have been putting it off and ignoring the mil light). When I first tried cleaning the harness on my car it didn't give me a problem for another year and a half. But I knew I'd eventually be changing it.
The other thing to keep in mind is that you should change out glow plugs as a set. It causes less problems in the long run since if one failed you will probably find other will soon fail and it keeps all the resistance close to the same value.
