Any Pug HDI gurus on here , got a mystery problem
Discussion
Hi good people,
Not darkened these doors for a while, however I was a very active member when politics made at least a bit of sense .....second thoughts ....
I’m trying to get to the source of a problem for my daughter’s boy friend’s Scudo van , I’m a competent home mechanic who has built a car from scratch and fitted a 40 year old engine with Suzuki Motorbike throttle bodies with attendant aftermarket Ecu . but I'm not a pro mechanic.
The scudo broke down and wouldn’t run properly let alone drag itself along, RAC diagnosed EGR and abandoned it . I fitted a new cheap EGR and it made no difference but once it warmed up it would at least idle but no response from the throttle at all , mechanic friend loaned me a basic fault code tablet to read the obd. Only fault that came up was glow plug fault . Tried blanking EGR and instantly started , idled from cold and would static rev to 2500 rpm , would pull itself down the road at up to 25 mph in 3rd. Fault codes then suggested MAF . So bought a new one , and fitted today . Car is no better and still no power . Any suggestions gratefully received . Does have a bit of injector blow by on no 4 but that’s been there a while I’d imagine . The van is 58 reg and shows 115000 km on the clock no service history I can find.

I spent a painful weekend struggling with a suspected turbo fault on a Scudo only to find it was the MAF.
I believe some cheaper sources may not be very good. Are you sure the new MAF you bought is ok?
To be honest no but I bought it from a respected local motor factor rather than eBay. My friend’s code reader showed the Original MAF giving flow readings but the temp reading was always around 30 deg C+ . and a fault code had thrown up briefly. Fitted the new one and no change , so I’m guessing they’re both working the same and you can guess both ok . Thanks for the inputI believe some cheaper sources may not be very good. Are you sure the new MAF you bought is ok?

Had all sorts of trouble with mine, eventually traced to the ECU.
Yes my tame mechanic has suggested ripping it out and sending it away for testing , he currently has a Cayenne Diesel running on 3 cylinders with the ECU sent away . Be nice to rule out simple (cheap) component failure first. Thanks Little Pete said:
If the vehicle is fitted with a DPF, it won’t be able to regenerate if all the heater plugs aren’t working and the soot content will become too high. This doesn’t always generate a fault code but the consequence can be EGR and MAF issues.
Wouldn’t cause breakdown on a long run though would it ?Farmer said:

Would you mind elaborating on the jump starting. Genuinely interested - even a link will do if you don't fancy typing it all out. Thanks.
Quite frankly....almost any jump start with leads on a modern car can be high risk.Inadequate leads, leads not attached properly or securely. Wrong polarity would be a whopper.
A booster pack is far safer, ideally with some sort of surge protection built in.

No mention of this in the OP, is this what happened? Any other info?
As I said it broke down suddenly and hasn’t run properly since , ran like a bag of spanners with lots of smoke and zero power , has gradually improved but still flat out at 35, so not nailed down the problem quite yet.Thanks

What fault code/codes are you getting?
A string of them , but it now seems the turbo has seized up which is probably at the root of all the other problems , there was definitely some movement last week so i'd ruled it out . this is extremely not a good situation for this engine I believe, Latest code seems to be P0402 and advice on other forums would suggest that's turbo related in many instances If it’s a 1.6hdi dv6 engine then yes it’s pretty common. If you are replacing turbo, you MUST remove the sump and check the oil pickup. 3 out of 10 we do have blocked pickup from lack of servicing. The oil feed pipe and drain to turbo must be checked, oil and filter changed. If you don’t, chances are you’ll be replacing the turbo for a third time
