Hi guys!

I need to replace the rear bearing, but I do not know the size of the hub nut. It is smaller than the front one.

Also, is there anything special to know when replacing a bearing? Anything I should be careful about?

Thanks!

Is there a forum post about changing an injector on this engine?

Has anyone here done this before by themselves?

So, it doesn't matter if those numbers are different?

The values on the scheme from my relay are: 3 1 2 5.

On ebay, I only see relays with high values 70-80.
Do they also work?
By the way, what do these numbers stand for?

Yes, I can.

I purchased the 109 relay from ebay, original product.
Can't seem to find the 100 relay though anywhere on the web

A link would be highly appreciated.

To any following this, I found what was the issue for the bad idle and the difficult start.

As Alex presumed it was a bad injector, it has a small malfunction and that causes the bad idle.

As for the heavy start, it was all because of the glow plugs it seems.

The guys at the shop recommended ...

Ok, thanks for the tip.

Buying one from ebay would be ok, or should I search for those only at VW official dealers?

I've read that the black version of the 109 relay has issues. My car has the grey one. Are there known issues with this one also?

Ok, decided to take it to service, the guys checked the car, 2 glow plugs dead, need to replace.

The wiring was good it seems just didn't check them the right way.

The mechanic told me I should also replace a certain relay, responsable for the glow plugs. Is it the 109 relay ?

Hi guys!

Yesterday I thought I should replace the glow plugs as they seemed to be the problem for the difficult start in cold weather.

After I took them out from the engine and tried them with the ignition on I noticed that none were working, tried the same thing with the replacements same answer ...

Yeah, that's correct, glow plug

Edit:

Figured it out myself. The size is 10mm.

Cheers!
