Really need some help guys!

Recommended Posts

Hi all, I recently posted on here but not had much help so I will try and keep this as short as I can. I purchased a 2014 Transit Connect Ltd with 54,000 and full service history. After buying the van I noticed the coolant tank dirty and low on coolant, when I opened the coolant bottle there was a huge amount of pressure released and the coolant would bubble up to the max line on a cold engine. The van started and drove lovely no rough idle no overheating and no smoke whatsoever but wanted to get it checked out so I took it to fords and they said possible head gasket failure! I then took it to a specialist for a 2nd opinion and they too said head gasket failure. I have the job to these guys and 7 weeks later they still have the van. This is what they have done so far:

new head gasket

skimmed head 

engine flush

new cam belt & water pump

Oil change and oil filter

fuel filter 

All the new parts are genuine. 
 

They called me yesterday to say the van is going into limp mode due to an over boost and need more investigating to see what the problem is. 
 

Do any of you guys have any ideas as I’m fighting a loosing battle now.

They've probably just left a plug or pipe loose somewhere.  Boost solenoid would be the first place I'd look.  Then MAP sensor. 

7 weeks unused might even be long enough for the VNT vanes to have seized if they were already sticky.

They finished the work nearly 3 weeks ago but they are struggling with the overboosting as they have gone over there work again and again and keep test driving it now. Do you think I should throw a new turbo at it?

New turbo probably nother £800 but after all the work you have had done so far yes as engine will be as good as new. Least you will reap the benefits & will then give you at least 5 years trouble free motoring - just other wear and tear parts to consider brakes suspension etc.

I have spoken to the garage today and asked them to fit a new Garrett turbo and go from there! ***** van the bill is already at £1800. The Machanic has said it might be the egr too but I have left it as change the turbo first. This van has only covered 54,000 miles I am totally gobsmacked on how this  Diesel engine has gone to ***** already. Apparently it’s the 1.6 DV6 engine and they eat turbos if you don’t have the oil changed every 6-8 thousand miles and remove the mesh filter out of the Banjo bolt.

If it is the newer 8 valve DV6C, then stick with it, it looks to be reasonably robust engine. As the van is 2014, it should be this version. The old 16 valve DV6 was phased out around 2011. A lot of the general information on the internet about turbo failure etc. relates to the old DV6.

The DV6C was a top to bottom re-design, with hardly any major common parts. That says something about the depth of potential problems on the older engine.

If it is the old 16 valve DV6, then it is very, very sensitive to any lack of maintenance. And I would imagine that for the average Transit, lack of maintenance is very common! I suspect a new turbo would be a total waste of money, unless the engine is fully stripped down and all oilways very thoroughly cleaned. There are plenty of tales of repeated turbo failure on these once they start to coke up.

How long have you had it? don't want to preach but buying from main dealer gives some warranty even if more expensive!

This is the van & engine it’s like brand new in every way. I have only had the van 2 weeks then realised the coolant did not look clean like my mates one

I believe it’s 16v that’s what it states on the totalcarcheck report.

Oh dear.  I was also expecting it to be the 8v on a 2014 model.  They must have chucked all the unused 16v's in the Transits!

There's no way I'd change the turbo for an over-boost fault.  When the turbos pop they don't produce any boost at all.  Are you sure it's overboost, not underboost?

Ford never fitted the older 16v dv6 in the 2013- transit connect. Will be the 8v . They need to recheck the boost control solenoid and vacuum pipes .

Just phoned fords to confirm and it’s an 1.6 8v DV6

Phew!  Can almost guarantee it won't be the turbo then.  They rarely break at all on this engine.

As said before, and Ian's just mentioned as well, boost solenoid needs checking!

So shall I tell them to hold fire on the turbo? Just check what you have all stated? Sorry I’m not clued up on engines.

Did the garage suggest it was the turbo?  How did they diagnose that?  

The only problem with a turbo that can cause overboost is stuck VNT vanes.  But it's unlikely at such low mileage and even if it is that, they can be cleaned rather than having to replace the whole turbo.

So we can assume that it's the vane controller that's the fault here, not pulling the vanes when it should.  That means that either the boost control solenoid has been left unplugged, or the vacuum pipes have been left loose or damaged.  That's definitely the area I'd be looking at.

No I’m just fed up with not having the van back so I thought maybe throw a turbo at it. They had 2 codes come up when they scanned it and I will get them Monday when they are open. Think 1 of the codes meant stuck actuator but apparently it’s not stuck. The van started and drove and ticked over lovely before it went in but the high pressure in the coolant tank needed investigating and when they done the head work they phoned me and said it looks like someone has already been in there and done a poor job on the head. My question is with such low mileage why has it been done already? Now it’s been done properly could it be done to a faulty turbo all along.

As you've only had the van 2 weeks before it being looked at, I'm assuming your not paying for any of this work?

A lot depends on whether you can trust the current garage. There are plenty of cowboys out there, including lots of Ford Dealers. What they are saying is quite reasonable. Once a duff mechanic gets down to a big job like a head overhaul, it is likely there will be other faults left afterwards. But it is just possible they could be trying to blame others for their own poor workmanship. 

Like Tom, I don't see how the turbo itself can cause overboost. It must be the actuating system (solenoid etc) or the vanes.

Looks a nice van, so it should be worth having the work done, even if you have to pay for some of it yourself. But the dealer should pay for most of the work.

The van is stunning and like new! I purchased the privately and the bloke I got it from owned it for 3.5 years and never had any problems and it is fully serviced. Like I said at the beginning I only had it looked at because I have never known that much pressure in a coolant tank on a cold engine, other than that there was no other signs, no milky oil no over heating no smoke or steam from the exhaust and drove fantastic!
