Hi guys, we have just bought a superb on a 07 fitted with the cursed 2.0tdi engine. As you will have probably guessed from the title its suffered the common oil pump failure and we now need a new engine for it. My question is will any other of the vag range cars be fitted with the same engine that we could swop over all of our ancillary's and get it running again? Any help would be greatly appreciated

A 1.9 AWX or AVF from a Superb, Passat or A4 will fit but not without some adaptation. It's better to have a write-off donor car as unexpected bits will be needed, also some coding. Very preferably, swap the engine and (manual) transmissions together. The 5 speed (GGB) transmission is far better than the 6.

 

Given the residual values of these cars, the job's hardly worth doing.

Looking for another 2.0tdi, just wondering if one from a passat/golf would work

If its same engine code, I cannot see why not, with some ancillary swapping perhaps.

Fitting a transverse 2.0 PD into a Mk 1 Superb won't work. You need an engine which is dressed for a N-S installation. There are too many differences (crank spigot bearing for example) to make a swap from a transverse car economically feasible.

 

The only N-S diesels worth fitting are the 1.9 AWX/AVF. Don't underestimate the difficulties in making this swap - check EGR actuation for instance. You need a donor car and the job is just not worth doing for the value of an old Superb - there's hours of labour involved. 2.0PD Superbs need to be scrapped now.

Think were going to do the original engine up, re grind the crank/new shells. Labour isn't a issue as me and my dad are both mechanics. Will probably cost less to do aswell than a new engine/conversion

We also gave very little for the car so don't mind spending abit. Its to Nice of a car to scrap as its very high spec

The spec of the trim makes no difference to the economics. If you put a lot of labour (and money - the bits are not cheap) into a 2.0 PD, you are left with the original design fault which is a badly designed oil pump drive system. The 1.9 does not have this problem.

 

There's no sense in spending good money on an obvious lemon.

Unless you like the car enough to be happy to spend some money on it.

 

And if you're mechanically competent, so can mitigate the labour cost, even better.

 

And if you look to improved oil pump drives, so it becomes less of a lemon, more even better.

 

Horses for courses.  Good luck with the engine rebuild LN88.

Well said v6 tdi, labour cost isn't an issue rotodiesel. Shells, regrind and new pump will be far less than the 1.9 conversion. The oil pump problems are of old, I'm sure they'll be some upgraded/re-designed pump buy now

I'm sure they'll be some upgraded/re-designed pump by now

I'm sure there are other options listed in other people's failure threads on here too.

I'll wish you the best of luck. I've seen this all before - it will either end up as a job you never finish, or else it will be a complete can of worms due to the possibilities of hidden damage, incorrect assembly or poor quality parts. The oil pump drive is a time bomb - some people have had replacement 2.0 PD engines fail following replacement of the original. Add a turbocharger to your parts list...
