Hi guys, 

 

Took my e61 535d to two independent specialists and had two different solutions presented.

 

First one connected a diagnostic and a whole load of faults popped up with regards to DPF/ glow plugs/ air mass/ charge pressure/ exhaust pressure. He then, Took off the engine cover and checked the vac pipes and said they looked bad and that he couldn't see the two rods from the bottom of the turbos moving when revving the engine. Told me to have the pipes replaced first before going down any other route. I do have a 4 star warranty but this will not cover such components like pipes and plugs. Nice chap, didn't charge me a penny for his time and gave me the option of contacting him if Iwanted to go ahead. £140 labour plus the pipes which I said I can get at trade price too.

 

Second garage, looked at the pictures I hadtaken of the diagnostic and said that the plugs replacement and pipes etc would cost me £560 and can get me in next week. Now, I know it may seem that the second garage is trying to take advantage of me but what could the issues be?

 

Obviously I would like to keep as much money in my own pocket. If the vac pipes aren't doing their job then replacing those first would be the most efficient option before going through the warranty company which would want to wriggle out of paying anything??

 

Anyone else had similar problems or knows which garage to trust? 

 

Any help would be appreciated and please forgive me for my naivety. 

 

Thanks.

 

Ams.

I wonder what the first garage would charge for doing pipes and plugs combined? Probably worth getting a price from them before making a decision. It may be false economy to get the pipes and plugs done separately due to labour costs.

First garage seems great to me.

 

Your real issue is almost definitely the vacuum pipes. Get them fixed and the car will be transformed.

 

The glow plugs are pretty secondary. If you want the car perfect then get them done. If you don't change the glow plugs in practice it only makes a small difference when it is really, cold, like -5C or below. Even then without glow plugs the car will start, it'll just be a bit lumpy for a minute or so.

 

As said above if you are getting the glow plugs done then get them done at the same time because the intake manifold has to come off for vacuum pipes and glow plugs and taking the intake manifold off is a lot of the labour cost.

 

If doing the glow plugs then there's a high chance the controller has gone so perhaps £120 for the controller and £15 x 6 plugs added to the parts cost.

Glow plugs affect the fuel economy and dpf filter. Since you have dpf error it means most likely without you knowing the thermostat is bad, hence the dpf errors. Check the coolant temperature, I am pretty sure it reads anything below 81 or so... for 535d it should be 92, at least it says it on the thermostat itself. Worth doing it since the manifold needs to come off as well. you need to change the EGR thermostat as well.

The thermostat is rated at 88 so anything 86 or above is acceptable at 50mph cruising once up to temp, that speed gives the best results.

Only use genuine stats as the shit ECP offer keep snapping the retaining clip as I managed to convince a guy this week who wanted to do the gearbox stat mod without testing if it was that, see the attached pic for his month old main stat.

Sorry mate think your wrong there as you don’t need the glow plugs to be working for regen. Long as your thermostats are good and running to correct temperatures it will do a regen.

+1 plugs are only to start it, on some cars they light up to increase temps during a regen but I have never read anything related to that and the E6x cars.

 

Engine stat is set at 88, car will run between 86 and 90 normally, it will not regen below 75c.

Only emissions related faults stop a regen

My glow plugs don’t work and passed its MOT today. Passed on 0.03 so happy days

The nightmare continues......

I took it upon myself to take the EGR off and give it a good clean as well as the throttle. Put it back together and hoped for the best...... same sluggish performance so the next day I went back to the garage that did the vac pipes etc.

 

He plugged in his diagnostic and a load of faults popped up again!

 

He's pretty sure that the actuators/rods aren't working as they should.

 

Could it be the turbo pressure valves?? Here's the pictures from the diagnostic.

You need to vacuum test where the pipe connects to the vac pump, only way to rule it out. I have an inexpensive kit for this reason.

I had an issue with my turbo just after I bought my car that threw up all those errors. It was a very simple fix for my turbo but I think the M57 is a different type, but it might give a clue to narrowing down the issue.

The linkage between the turbo actuator and the VNT lever on the turbo had jammed, locking the turbo vanes. I loosened it up and a blob of high temp. grease got me out of that hole. I went to the stealers for a new linkage kit for about €12. Five minute job to replace.

There are three actuators on the 535d and if the vacuum system is perfect (usually it is not) then a jammed or disconnected actuator will cause havoc.

 

Usually though it's a vacuum problem or blocked DPF.

 

Then it could be a clogged MAP sensor.

Hi guys.

 

I've made the decision to have the DPF removed. Found a company local to me that offer this and a remap to 320bhp for £399. I've asked him that I'd have the DPF removed and then drive it for a week to see if the other issues clear before the remap. He advised the same thing. Thoughts??

I would ask him to map out the regens for the DPF after its been removed.

Edit - Plus map out your EGR as well :-)

Ok, thanks. Do I need to go to a bmw specific garage or will a generic remap be ok? Read a few different reviews about this place and now I'm not 100%.....

This guy, he tunes the car, no generic maps. He has agents dotted around as well so worth asking.

Cheers for the referral....

 

I've booked the car in for DPF removal/hydro flush and a remap. Should see 315hp and 650Nm but more importantly; an end to this nightmare! DKU performance in Walsall are the guys hooking me up. 

 

Let you know how it goes.

Going to the initial post, I don't think the actuators will move by just revving it.. I'm sure mine don't..

There are 3 actuators,

Large turbo waste gate (not be confused with variable vane 525d/530d)

Inlet airflow small/large turbo

exhaust flow.

The change from small to large turbo is around 1800-2000 rpm. The small turbo is boosting almost from tickover.. My DPF is removed and you hear it on tickover whistling

315bhp and 650Nm is a very conservative increase but if done correctly will return better MPG

So..... after a whole day of going to 3 different garages, a wizard by the name of Harj has found a split in the intercooler pipe!!!

 

We were both amazed at how 2 other 'BMW Specialists' didn't see it/check for it in daylight and yet he clocked it in the dark with an led head torch. Anyway.... new pipe should be on tomorrow and hopefully it will sort the power issue out. Still scheduled for a dpf delete and remap on Monday. Gonna treat the ol' girl to some new 19" wheels too. 

 

Keep you guys updated.
