A friend of mine is after an engine for her A4 Cabriolet. The crank has broken, a previous owner has fitted a solid flywheel, I believe a broken crank was a posibility after such a conversion.
We've been in contact with a local VW specialist who tells us that the Cabriolet engine is "different" from A4 saloons/Passats but won't go into detail. Is this the case or are they just trying to bump the price up? A Cabriolet engine is 3 times the price of a A4/Passat engine.
Thanks in advance,
Jon.

That sounds unlikley, get the engine code off the old one and do a bit of googling. There shouldn't be any difference as VW don't generally work like that.
Solid flywheel conversion is just cheap and sometimes used when owner wants to reduce costs. May have been the old DMF was past its best and rumbling away and vibrating. Solid flywheel set up is usually much cheaper, that doesn't mean better though.

Wiki suggests the B7 Cabrio's came with 2 versions of the 140bhp 2.0TDI's "There were two different versions – one had an 8 valve cylinder head the other had 16 valves. They had the same power and torque output and performed equally. Customers could not choose directly between those two engines. They got the 8-valve version when they ordered the DPF otherwise they got the 16-valve version (BRE engine code). In many countries the DPF became standard equipment for all B7 diesel engines from model year 2006 on and the 8-valve engine was no more." en.wikipedia.org/wiki/Audi_A4But all A4's were available with that engine, so it could just be it's the less comon version of the engine. At least it's not got the CVT gearbox as well, took my mate (mechanic) 18m to track down a used one! |

There shouldn't be any difference as VW don't generally work like that. VW work exactly like that. They make about 15 different "versions" of the same engine at the same time for absolutely no reason that I can fathom. Externally they're almost the same apart from usually one slightly different mounting boss on the block or a pipe in a slightly different place. It's bloody infuriating sometimes trying to replace like for like if a major part is scrap. |

Thanks for the info, I have found a list of engine codes so on Sunday I'll check what's there. By the age it should be a 16v BBE.
I've been out of the motor trade 16 years and get a little lost with modern stuff. I'm not doing the job, I don't want to see the lass get shafted with stories of "special" engines at £2k fitted.
Thanks again
Jon.

Problem with dual mass to solid flywheel conversions is that the DMF often also functions partly as a torsional vibration damper and that function is lost. Indeed, quite often manufacturer sanctioned conversions (or where both exist from the factory) will have a different pulley assembly for the two versions, with an “uprated” one for the solid flywheel.
It’s the torsional vibrations (resonances especially) that break cranks and rattle gearboxes to bits.

If you want to PM me the reg number or VIN I can tell you what the engine code is. From my info here the BBE was a 2.5TD 5 cylinder 10 valve and only used in the gen 2 LT vans.
Sadly some of the solid flywheel conversions were not up to the task, usually because the drive plate didn't have long travel springs to damp the vibration.
