Mein Gott!
Was the TUV formerly known as the Gestapo?
little different to us making mods to our homes.
you have to prove that it complies to xyz.. or get a man in ....... who has the accreditation so can cert the work and send to the local town hall.

what do you mean by "tweak the remap to the waer level of Your car engine"?
My remap was customized and tested on dyno. So version 4 of the original remained. They changed some values on the remap to be more suited to my car. So instead of +50HP and 75nm i got + 65HP and +110nm of torque. Also they mentioned that it is not making more particles so dpf is not going to be needing more cleaning. So far I would say that its true, i hardly notice that is cleaning.

is that legislated?
e.g cars with X bhp must have discs of Y
There should be something but my logic was because XF S with 275ps comes in 355 as standard and 240ps version comes with 326, probably insurers could argue braking power is not enough to stop a car with that HP within spec.

sorry, just realized I forgot to finish what I wanted to say in my last post.

So, as both 211 hp and 240 hp engine variants can be software boosted to 290 hp, one would presume they are identical, hardware-wise. Also torque can be boosted to 570/575 Nm respectfully.
However the S model with 275 hp can be boosted to 325 hp and significantly more torque, so one has to presume that there are non-software components in this S engine variant allowing this to be achieved.

I have a weak memory that Michael onces said the part number for injectors are different. I haven’t checked though

Funny I have a week memory to Michael said there was no difference in the injectors parts and the difference was only software (ecu) :unsure:

I'd just do it...inform the insurance Co and enjoy.

I think you may be right Gav.. I also 'seem' to recall the differences work along the lines of it's the same 'bare' ECU/PCM until programmed on the production line and can't be reprogrammed afterwards, the workshop manual definitely says that the ECU/PCM has to be new as a used one can't be reprogrammed, I read that part this afternoon.

It is probably true that dealer level SDD can't reprogram a used one, probably not even JLR tech specialists, with their higher level SDD access, that get sent out to help troubleshoot at dealers can't either.. but, I'll bet JLR very senior technicians/developers have access to the higher levels again to be able to do that though.. but would never admit it..

@08292 & @Onotole may have the knowledge.. or at least have a good idea how you may be able too...

I could be wrong. I will doubt check tonight.

Interesting. We have similar encrypted software for our high-end fluorescent microscopes that only Zeiss/Leica have access to, not us as end users or our technical support staff.

Someone from the garage replied asking me to call him to discuss the remap of my car. He said that they would not usually remap such high mileage cars - but, after reading my description of how the car has been maintained and the recent work on manifolds, DFP, injectors etc., he wants to discuss our options.

How much should I expect to pay for a full remap, including before/after dyno readings? I would like to be prepared ;)

So I looked at new injectors for my car (Bosch CRI318) and they seem to be for all 3 power versions of XF 3.0d:

183806

Yes that’s right. It only changed in x260 regardless of power output

I just called the remapping garage and had a very good impression from the guy there.
He wanted to know a lot of details and said he would first like to perform several tests on the car beforehand in order to decide exactly if and how to remap to give the optimal performance boost, focusing on torque. He said that he would not give a full 190 PS power upgrade in order to prevent potential stress related damage, but concentrate on optimizing several parameters to achieve better overall driveability and performance. There would be a guarantee for engine damage related to any upgrade done.

Bad news is he wants € 700 Euro (almost £ 600) for all the work.

I will go beginning January for him to do the first test on DFP and injector conditions, than we make a decision if all OK.

He also wanted to know the exact model Nr. of the ECU so I had to remove a few things again to gain access and discovered that is different from the information they post on their website:

Built in my car: Bosch 9X2Q-12A650 - EQ9GE A0105

On their website it states the ECU is following: Bosch EDC17CP11

I have an appointment on Monday 11th for a remap of my car.
He wanted to have more information on the exact model number of the ECU in my version of the 3.0d.

After looking closer, the Bosch ECU number (0 281 014 671) appears to be the same for all 3 engine versions (211, 241 and 275 PS). So, basically everything is the same hardware speaking and software instructions make the difference, at least for pre-facelift.

He will tune it for optimal drive-ability/performance based on the current performance it has (important for higher mileage engines). I will keep you posted next week when I get it back. He reckons he needs the car for 2 days to get all the testing and optimization completed.

Dropped car off at tuning garage this afternoon and had discussion with guy, who was super friendly and wanted to know a lot about history of car and it maintenance. He seemed concerned about fuel in engine oil but I assured him that my oil level has never increased significantly to my knowledge, which is true. He was impressed with my knowledge and what I had done recently to engine (Intake manifold renewal, MAP sensor renewal and injector cleaning), but mentioned that I should probably not have dismantled any injectors as they are difficult to put back together properly.
He will anyway run a complete diagnostic test of all systems on the DYNO (engine performance, gearbox performance and exhaust performance) before deciding on the optimal ECU parameters to change.
I told him I wanted better low and mid-range torque improvement with quicker gearbox upshift and not so interested in overall top speed (can already easily get it up to over 200 km/h on motorway without pushing too hard).

He just texted me now that he has found 3 faults on the ECU:

184115


However he mentioned that this was not serious and should not be a problem for the remap. He also said the engine runs really nicely, so happy to have independent confirmation of this.

Lets wait and see if everything is OK on the actual DYNO test.

Sounding good there!! Was there a 'time stamp' on the fault codes?

Not sure about the time.
He told me these faults appeared twice when he put the ignition on, without starting the engine.

The "Geschichte" means it was a historical code I presume.

The P2586 Turbo codes would have worried me most but he does not seem worried.

So car has been optimally remaped to my wishes of providing more low and mid-range torque.

He called me to say he has never mapped a car with so much potential and he had to stop himself from powering it up to around 300 bhp! Bloody hell :oops:

Good news is that he told me the engine runs very sweet and everything is in excellent working order so I am extremely happy and looking forward to picking it up later today. He is road testing it now.
