Thread: So the PUMA goes back to the garage again tomorrow

I have an SVX and wondered that if I really need specialist advice on the engine I might not get good expert advice, on the engine at least from FORD.


These engines have been on the road for years and done billions of miles in transit vans, they have little to prove, but debugging an intermittent fault might be easier for a ford mech.

Even if were simply for a diagnoses.

That's all well and good but they are not exactly the same as what is in a ford as ford gave the engine to landrover and they redid a lot of stuff to get the power&torque etc out of it that they did. Plus there are parts on the engine that were redesigned and made by landrover.

Infact I believe that ford were so impressed what the land rover engineers had done to the engine that they took on the designs to reincorparate back into there transit.

Funnily enough I think the vacuum pump was one of the land rover redesigned and built parts........ and it failed

Edit: As far as I'm also aware transits have had a lot of problems with the EGR...

The one problem I have with engine knocks is that they are very common in most or if not all new T/D's.Why that is I don't know but the D4D is renowned for it and the three I have had for work vehicles rattled quite badly,one was almost like detonation at start up.Does the engine knock when cold or all the time?. Pat

Doesn't knock on start up and tick over....and its not really a knock its a machine gun rattle. (possible detoantion) and only does it as its about to hit boost 2000rpm only in the morning and when its cold and or damp. it happens every morning unless we go out when it has warmed up a bit late morning and the car has had the sun on it.

once it has done it it will not do it for the rest of the day.......

Although the newest thing it has started doing on occasions is it will do it again 50 meters up the road. this has never happened in the past, in the past it used to do it once and if it was bad enough go into limp mode.

And believe me, I take it out of the loan car's @rse in fuel and wear and tear . I think the last one may not have even made it from the dealership to the servo for its next fill up .

Yup "x2" , MLR have always provided me a courtesy car for Warranty work. (Even if it is a clapped out Ford Focus - although got a nice D3 once)
Good luck with the pooma DB.

What you have described is the identical thing that most D4D owners say.IMHO I think it is the high injector pressure that causes the fuel to burn quicker as it atomizes faster and more completly than earlier engines so that they have a ''harder'' diesel knock.They get the power through getting more punch out of the fuel.

Just for the record, my "rattle" is still there although it has only happened maybe twice since the EGR was replaced back in March. I am watching it like a hawk now that weather is cooling down. I'll be sending it in for the vacuum pump to be replaced sometime in the next week or so (fortunately I only have some oil seepage, not the explosive failure others have had). I will be asking the dealer to run a diagnostic check to see if any fault codes have been recorded.

I am suspicious the reason it has only happened twice since the repairs is more to do with the fact that I have changed my usual morning driving routine. Since moving house I am closer to the main road, so the vehicle is on the accelerator sooner. Before it used to always happen at the same stop sign in the morning, when coasting to a stop, or at idle. Now I don't have any stops before getting the vehicle up to speed so it's warming up quicker.

My dealer seemed pretty convinced it was the EGR, hence the replacement but I will be keen to know what, if anything, your people find.

Hi DB, my 110 does exactly the same thing, although its never been bad enough to cause it to go into limp mode. The dealers haven't been able to replicate it, and it hasn't been cold enough for it to happen again this year.

My 110 will usually do it when I change from 2nd to 3rd when I first drive away from home in the morning, I've found that if I'm not carefull with my gear change and have the rev's too low when I change into 3rd and "bump" the rev's up I'ts far more likely to happen.

All the best with the dealers, I've found that if you suggest something, (ie that the egr is at fault), they will look at everything else first! Best just to drop the car off, drink their coffee, and demand a free loan car!
