It is to a standard TDV8

I need some more cylinders to keep up with a mapped TDV8

No chance Mikey!

Had a massively tuned TDV6 D3 for the past 4 years (recently sold) and they can in no way be compared sir!

I beg to differ. Although I should have said RRS, which is a similar weight to the D3. The FFRR is a fair bit lighter than D3/RRS

My D3 is making almost as much power at the wheels, as a standard one makes at the flywheel

@ziggy
regarding improvement after blanking, yes but I have no measurements to prove it.
It feels a lot better at low RPM's, less turbo lag. Up here we are at 1500m above sea level, so the lag on a standard vehicle is quite noticeable.

Just for interest - thought the gear heads amongst you might like to drool a bit. A few things my friend Dean did here, blanked the EGR, a bit of smoothing inside the exhaust manifolds, ceramic coating, and a big intercooler. Haven't mapped it yet, he wants to drive it for a week or so to make sure its reliable before we start getting serious:

My bmw 120d was recently down to about 5hp, with check engine light on. 1st gear...max of 3mph. First job...clean erg valve. Easy, dirty job and very dirty. No improvement, but looking inside the inlet manifold, etc. showed everything deep in a the black sooty stuff. So its the turbo.

Just about to remove the turbo to see what the damage is, as it looks like the variable vains and actuator are not moving (more black soot?)....A turbo for 120d is about £700 fitted, for the two turbos in my 3.6 FFRR, quote about £4k! Engine out job, mechanic says. So keen to see what can improve the situation and if I can learn anything from the 120d.

Looking to blank/map out egr valve. Found local(ish) company that will map out both erg and dpf. Any thoughts from anyone who has done this? (egr/dpf map out and physical blank/removal).

Any experience of the company, pnp autofix, in Peterborough?

Spoke with MOT tester last week and they now are checking DPF's are functioning as part of the MOT so... NO you cannot remove or MAP it out or it will fail the MOT

As above

DPF has to be fitted for an MOT, and the EGR has to function in order to regulate the temperatures for the DPF regen

No idea if the DPF can be gutted, and mapped out though. Could always find a friendly MOT station

OK, accept that Particle Filter has to be there for the MOT... (being there...might be different from mapped out and/or hollowed out. Thanks for the suggestion.) My journeys are 99% duel carriageways and I will never drive in London, etc. Looking at the method and theory can't see any increase in emissions, or evil particles of significance with or without this filter during the remaining life of the car.

How about the erg? MOT test checks emissions rather than erg working. Lots of examples of MOT passes with this blanked/mapped. (And if caught, i.e. emissions not quite right). Just remove the blanking plate and go back for a retest? Any thoughts?

Sorry to resurrect this thread but would a failing EGR valve cause an "ENGINE SYSTEM FAULT" that IIDTool reports as a turbo actuator fault?

I'm getting this occasionally and more often than not, switching the car off and on clears it. When it happens , the car is down in power and a bit stuttery. Got - 2017 SDV8 Autobiography in Loire Blue

Oh dear Alan, that sounds worrying sir... As I’ve said before... I wouldn’t risk driving a 3.6 with any turbo/egr related fault! Most that have, report they can turn it off and reset when re-starting so have continued using the car, usually until it gets worse/more irritating then finally get the fault looked at! The EGR’s get changed and within a very short space of time the R/H Turbo will (at worst) explode throwing its internals back through the induction system...

This IMHO (backed up by many professionals in the turbo world) but argued by a few on here! Is due to the Turbo being over-sped or over-spooled... Therefore creating a second issue “just waiting to pounce"

It then becomes a lottery as to how much it takes with it! Just the induction system (intercooler etc) or the whole engine!

Sorry to be the voice of doom!

So what do you recommend in this situation Craig?

Leave it and not get the EGRs replaced and run the risk of the turbo lunching itself?

are my symptoms more likely to be EGR related that manifest as turbo actuator faults? Got - 2017 SDV8 Autobiography in Loire Blue

@ alanm_3

My recent experience is very very similar to yours. My local indie suspected the EGR's and the lack of power / slight misfire under load seemed to fit the bill but they were completely happy with their diagnosis and advised I may want to get a 2nd opinion. BTW - we'd made sure the actuators were moving freely on both turbos.

I took it to one specialist who diagnoses the control module on turbo No1 as being the fault so I told him to get on and repair it.. I'm still waiting for the call back when a courtesy car is available.

I took it to a 2nd specialist who, knowing I was desperate booked it in a week later but then just told me it was the RH turbo and he would need to book it in to do the work Waited and waited but nothing despite, like the first specialist, chasing many times.

In the end i bought a turbo from Fast Turbo, took it and my car to my local indie who fitted it one Thursday afternoon and hey-presto car's back to normal now.

Loads and loads of frustration but.............Got there in the end despite so many "specialists" not giving a damn about customer service s

Anyway, I guess what I'm trying to say is get your codes read first - it may be a turbo actuator issue, like mine, which isn't as bad as you may think

Good luck!

Yes, the errors are related to the turbo actuator and like you there are as many theories as people who look at the car! I just wondered if the EGRs were the cause of the apparent turbo actuator error. Cause and effect etc

My local Indy immediately called out the O?S turbo as the external actuator moves freely, however they told me there's an electrical actuator inside the turbo that can only be replaced along with the entire turbo assembly.

Out of interest how much did you pay for the turbo? ECP have them "on sale" for just under a "bag of sand"  Got - 2017 SDV8 Autobiography in Loire Blue

As said above Alan, its not a forgone conclusion it’s one or the other, or even related to either! & i would only be guessing if i advised you further So... You really need to get it checked out by someone knowledgable asap...

That's what I did when it first appeared Craig, but as has also been said, opinions differ as to what the reasons are for this issue.

I don't want to fork out for EGRs only to find a turbo destroys my engine, so should my first port of call be the turbo on the basis that if it's not that and I have to replace the EGRs, it will almost certainly result in a turbo failure? Got - 2017 SDV8 Autobiography in Loire Blue
