Your motor code is GU,

My VW manual says that with a new a GU, 1P or PF motor the compression should be between 10 & 13 bar, the minimum pressure for a used motor is 7.5 bar, with a maximum difference of 3 bar between the cylinders

For the GX & RP motors the figures should be new between 9 & 12 bar, the minimum pressure for a used motor is 7 bar, with a maximum difference of 3 bar between the cylinders

Yes, when LD50 & I were at the house last year, showed us the foto log of this conversion

There are no individual spare parts available from VW, so you will have to replace the complete pump, but as they cost well over 300 pounds each new I think it may be time for a trip to the scrapyard, or you could try & replace the front seal if you can get one from a bearing/seal supplier.

They all have to have a lambda input on the 2E motor or they go into limp home mode,
btw all the lambda does is to constantly fine tune the fuel mixture so it is at the optimum burn ratio all of the time, so there is no excess unuseable fuel or air, I.E too rich or too weak

[Chris S]

Also check the propshaft bearings

[Chris S]

The Golf & Passat Syncro models have permanent 4wd, as Holmes says it could be your rear brakes binding, jack the rear up & see how easily the wheels spin,
btw, they will only spin 1 way if the front wheels are still on the ground, as the 4wd prevents them from turning the other way.

[Chris S]

That nr is also ok, its the computer for the catalysed motor, it is as are all 2E motors/management computers meant to run with a lambda sonde.

[Chris S]

As long as your ECU box has either 037 906 022GD or 037 997 023SX as the part nr then its ok.

[Chris S]

The only slightly annoying thing is I never got to try out the hard-won K-jet dizzi, on the Weber – it was supposed to have an aggressive advance curve on it. Ahh well, on to bigger and better things

Exactly just make sure it is lambda controlled, then I have a nice 10/15 bhp chip for you

[Chris S]

The front springs are a direct swap, but I will bet money that the rear ones have had 1 or more coils cut off to make them fit,

btw dont worry if they have, its quite a commom modification cos sport springs for the rear of a Syncro are virtually unobtainable,

Mine is running very sucessfully on cut down 11mm wire diameter aftermarket Passat sport rear springs.

[Chris S]

While that does make sense, would they even if they were asked not to? I do hope not.

[Chris S]

yes, but above 14.4 volts the battery begins to boil & lose fluid.

[Chris S]

The max voltage should be 14.4 volts

[Chris S]

Yes, its always nice to be appreciated, Thank you again.
