    What did you do to your E60/61 today?

    Hi Guys technically it was Thursday when i had the work done, only just had chance to post. I had the pleasure of meeting the wizard @Mashed Potatoes at Harper Autos http://harperautos.co.uk/ to have my ECU MAP read and cleaned up. Great friendly bunch of people and felt at ease leaving my car with them. Car feels completely different nice constant boost and smooth response with a improvement on MPG's. Before MP waved his magic wand the car was surging on boost and holding too long before shifting, was told that the turbo control valve was set up wrong. Anyway thought I'd big'up MP and share my experience

    Glow plugs again...

    I had the same issue, turned out to be the cable from alternator to relay. Like illustrated melted connection, I had 2 of the cheaper Beru relays then went and bought OEM still got faults occurring, was only when I pulled off the cable to inspect that it was obviously a cable fault

    535D issues

    Just to add on this oil grade.. My experience was bad with 5-40w. On cold start up id get a puff of blueish smoke and oil level kept dropping. Since going back to 10-30w I've not had them issues. Id like to know why people choose the thinner oil. I would think when a engine wears over time that the tolerance gap increases causing a need for thicker oil.

    E61 - Tyre Pressure

    I had this problem. According to the tyre guy he said its common with BM's.. Apparently due to the large width of the rear, when it runs at high speeds the center expands out from centrifugal forces causing the center line to wear out quicker. I very rarely have 5up in mine so i have mine a little lower for the size of my wheels 36psi on the front to take the weight of the engine and 35psi in the back. depends on your tyre brand and wheel size. Like i said 'for me' its working out well so far to have slightly less. Hope it makes sense to you because tyre guru had me when he said the word centrifugal....

    530d E61 Constant Engine Vibration

    Here's a method of checking for play in mounts. Open Bonnet Get back in car - Shift into drive (works in reverse too to check opposite side) Keep left foot on break pedal and massage the accelerator with your right foot observing the amount of movement or play from the engine. You can see the engine through the bottom of the bonnet in the open position or better still have someone do the pedals while you observe. Here's a nice article on replacement and symptoms of worn mounts. Just found this today, made me question mine.. https://www.youcanic.com/u/bmwgearhead/bmw-motor-mount-replacement A few videos on youtube will show what worn mounts will look like and how they will behave..

    DVD sat nav fault

    Mine had a stroke from the bad weather. Contemplated upgrading to an Android system, glad i didn't because i still would of needed the CCC repairing. I contacted this place in Bradford cost £450 to repair regardless of what needs fixing. sorted it out but begrudged paying that flat fee. Anyway just thought id share this repairer with you all. https://www.revtronic.com/

    535d power loss after 3rpm

    Thanks for reply Jushed I hear your frustration, its had me under the bonnet on a regular basis.. just gonna have a look at the DPF system and check vacuum before i decide what move to make on my puzzle..

    535d power loss after 3rpm

    Thanks for reply Khanny I've just ordered a pump so in a couple of days i'll break out the tools. I'm ok with the plumbing JasonH sent me some comprehensive documents on the Turbo layout. Will check them fuses too..

    Hi Khanny what are these fuses for pal

    535d power loss after 3rpm

    Hello Jason Didn't know about this sensor and pressure pipe, i thought it was silencer flap controller. Am i wrong about the there being a pressure sensor in the MAF as well, i am going from memory.. When i get home i will run DIS again and provide some screen shots. But yes when i scan the DDE for errors and clear them, i'll start the car straight away go for a run then switch off then back on followed by a scan. Scan throws up 41AB code every time.

    Thanks for reply Jushed I live up north in Merseyside pal but thanks for offering. Do you mind me asking what you were charged for the map alteration to sort your problem.

    535d power loss after 3rpm

    Juts picked up on this post..! Glad to hear that you resolved the problem. I've been running around in circles with this puzzle.. This is my approach to diagnosing, firstly my fault codes are 41AB Boost Pressure Sensor + 41ED Cyclic Authentication (2nd code is in Information history) INPA Software used to read faults. I've replaced all the vacuum hoses up to the Engine mount pressure converter, going beyond was too much work on the day i was working on car. I even replaced the vacuum supply manifold which now has its own supply to the Engine Mount P/C, i did notice the 4/way plastic junction feeding lights, engine mount and swirl flaps was bunged up with crap. I cleaned that it out and separated the feeds, I've replaced the Air temp sensor on the alloy air supply to intake pipe along with 2 MAP sensors. All seals from EGR to Turbo.. So a couple of things I've picked up using diagnostic software. 1.When looking at DDE status on INPA actual boost is higher than what it should be. (i was told the car was mapped when i bought it no proof to back up..) 2. When i clear the code and go for a drive the rev counter no longer jumps up and down erratically. ( i think this will be due to EGR being active , when a fault occurs in the DDE it stops the EGR and DPF regen) 3. When i use DIS the report says there's a difference of around 5mbar between the MAP/MAF sensors, the lower reading being in the MAF sensor. Now after some research i managed to pick up on a couple of threads using just the fault codes in Google search that some folk think its down to bad mapping. I dont have knowledge in this area but can imagine that some gains can be had through manipulation in the ECU. If this problem lies in the mapping then i will be in touch with MashedPotatoes to arrange a visit. Thanks for your advice

    Damn alarm!!!

    INPA software will tell you where the problem lies. Check the alarm module I'm sure its in the car safety section *correction* its in the body module.!

    Intermitting Starter Problens

    Ha... yep ... remove the inlet manifold... Talking half a day... Tried to source a replacement solenoid but got overwhelmed by selection. Unsure weather a BMW listed solenoid would be suitable for all staters, they are considerably cheaper than a complete starter. Thanks for your input Jason
