From memory (old and dodgy) should be around 50psi any thing lower will give the symptoms your getting If I remember Pelican Parts did some great write ups on Fuel delivery and pressure plus stuff on injector testing worth a look at their site I have been told it only hurts when you laugh 🤣 Get well soon Matey Dave- 1

Loss of power after service
Thanks Dave, the original map company don’t have a clue what could’ve happened as the garage shouldn’t have been able to do anything. I’ve got it booked in tomorrow somewhere else to take ECU out, see if the map is still there/gone dormant and remap if needed. I’ve just done a 500mile round trip fishing at the weekend to wales so I know for certain it’s not driving as it was and the fuel consumption for this journey I do 2-3 times a years has gone up as well as the car being lethargic. As for the headlamp washers…thanks, I’ll get new ones fitted. -

Morning William Welcome to the Forum First the headlamp washers, I beleive your headlamp washers are the same system as the E70. Which means you have a fuse to control the Headlamp washer pump but the actual washers are extended by water pressure retracted by spring, if they fail it's quicker and easier to just change them (I learned the hard way) As for the Map I think the only way forward will be to talk to the original Map installer they may know what has happened. Never heard of a simple service disturbing the ECU map but they may have seen or heard of it before (I did read on a Subaru Forum that a Garage tried to copy the map but that ended with a fried ECU) Dave -

engine judder while idle
Morning Not necessarily I recently had an injector fault that randomly shut the engine down no codes no EML The only way to find it was to actually run live data on the Diagnostic (INPA/ISTA) and drive the car when the fault occured I was able to record it. That was the only way to identify it Make sure you check for any air and vacuum leaks a small crack/split in a vacuum hose The inlet has several hoses that rely on "O" ring seals are they all good Dave -

Loss of power after service
Hi all, I have a stage 1 mapped 2010 330d touring which last Thursday went to my local garage for oil and filter with a look to also see if they could switch of the non retracting headlamp washers(unsuccessful)…I get it back and all seems well until I go for a drive, I’ve lost all torque, acceleration and rather than staying in gear and pulling away it’s dropping down gears to pull off. The garage plugged in a new snap on machine to have a look but said they couldn’t get in due to not having bmw software, they’ve had it back to see if anything is obvious but they don’t have a clue, couldn’t spot any vacuum leaks etc and no fault codes coming up short of the ones that indicate the swirl flaps/egr have been done away with. Other than getting it in too have the map checked to see if it’s still there I’m lost. It just feels exactly like it did before I got it mapped.
