I've been reading up on the very well documented oil pump failure problem of the 2.0 PD engines, what I cannot seem to find however, is a guide price on replacing the potentially faulty part to avoid it happening before it does. Any ideas? Has anyone done this? All I can find is prices people have paid once the damage is done

I researched and contemplated this and got quote from an independent specialist in the middle of last year, but in the end changed the car (yesterday) before it needed doing.

I've still got the written quote so here goes:

 

Pump & shaft is £115

 

Labour approx.4 hours max (assuming sump comes off OK - there is 1 bolt which is hard to get to and may be rounded off) It's actually a fairly simple job if nothing goes awry.

 

Ancillaries (oil, sump sealant etc.)

 

Total cost around £450 - Parts £150, labour cost will vary depending on local hourly rate.

 

If there is a problem removing and destroying the sump they reckoned it would cost around £1200, the sump is about £160, but if they had to break it to remove it there is an oil seal that needs replacing, cos it is damaged in the process, the gearbox & clutch has to be removed and replaced, and the oil seal costs about £75

 

In summary:

 

£450 if no problems.

£1200 if problems with sump removal.

Six pounds for the hex drive, 700-900 pounds for the turbo plus labour about 1300-1450 pounds all in. That is what my sons cost. That is without replacing the oil pump and I had the work done by a VW specialist.

The oil pump I understand is about 800 pounds on its own.

Sorry, that's wrong - I assume your pump had failed and starved the turbo of oil. Changing the pump as a preventative measure would not include turbo cost.

 

The actual cost of the oil pump and shaft is £93.38 plus VAT.

Hate to argue but it is not. What failed was the hex drive (it becomes rounded) to the pump as the hex drive metal is softer than the female section the hex drive is inserted into, that then cause the oil pump to lose its drive and therefore oil pressure followed by turbo failure.

What ever the cost of the oil pump it does not matter who is right that is what happened and what it cost to repair. The dealers cost would have been even higher.

Read the original post !!!

 

He is not asking how much it cost to replace your son's turbo which was damaged by oil pump failure.

The question was, how much would it cost to replace the oil pump as a preventative maintenance item BEFORE it fails.

 

Do you recognise the following from the OP:

 "All I can find is prices people have paid once the damage is done"

I answered the specific question he asked, namely how much does it cost to replace the oil pump and its drive shaft.

You gave him a repeat of the useless information he has already found

As you say then it is "simples" replace the hex drive is what the specialist told me which is part of what I said ( £6 plus labour is what they said would be preventive measures but how many people have gone to all that work with hind sight) but yes I did repeat what he had found out and i am sorry if it seemed to upset you but as this is a open forum that some times happens and is not meant to upset people it is simply what people and I was trying to help in my miss guided way.

The root cause is not wear on the oil pump drive shaft (3" hex rod). The problem is with the drive splines (lack of concentricity) on the balancer unit. That's why if the balancer unit isn't replaced, the problem will occur again, even with the newer, harder drive shaft.

Correct. The oil pump is well made by an outside supplier and the hex drive shaft is well fitted and engaged with the pump inner rotor.

 

What is unbelievably bad is the degree of engagement of the (male) hex shaft with the hole in the end of the slave balancer shaft. It appears that for cheapness, VAG drilled 6 small holes and then bored the centre out to make a "hex" hole. There are also concentricity problems. Their bodged fix was to (eventually) lengthen the hex shaft to 100mm and to improve the slave shaft bore and its concentricity. My judgement is that it will still fail - but take a bit longer.

 

The real killer in all of this is torsional oscillation - caused by the weighted shafts. After all, that's what they're there for - to provide out of balance forces to counter those inherent in a 4 cycle 4 cyl engine. It is the torsionals which destroyed in short order the original chain drive, and it is the torsionals which also finish off the lousy fit of the oil pump drive.

 

In short, shoddy engineering designed by people with no knowledge of the dynamics of a balance drive, and non existant back up from the vehicle supplier. Draw your own conclusions - would you buy something like a DSG gearbox from people like this?

 

Remember, these drives were failing on Audi badged vehicles before the Superb was born.

@Roto

On the last balancer unit I replaced, the hex socket had been broached as the grooves weren't rounded. Prior to that, there is a rumour that as many as 5% of the units failed QC and were junked. That's probably why I haven't seen a repeat failure after changing a balancer unit.

Anyone know what the part and labour costs of replacing the balancer unit is? Ball park figure would do
