Hi All, It's been a while since I last posted on here, but I thought I would share with you an issue I faced with my car last week, the terrible advice and technical knowledge I got from Vines and my pleasure at finding sound advice from BMR Turners Hill West Sussex... So my F11 LCi 525d went into limp home mode after its service last week at Vines of Guildford, so I took it back to them. They did a diagnostic and was told either the intake manifold actuator had failed and was not activating one of the swirl flaps, which would be replaced under warranty or, if the actuator has failed due to the engine being coked, then I would need a replacement intake manifold and have an engine de-coke which is not under warranty. What made me question Vines BMW methods was they said that they needed to remove the manifold to determine whether the engine was indeed coked which would be 3 hours labour and once they had removed the manifold I was committed to any repair. This is simply nonsense, and I told the service advisor as such. A simple compression test would be able to ascertain whether there was a coking issue and secondly the manifold was a single enclosed item that had a few bolts and could be removed in 10 minutes and thirdly if you are able to ascertain that there is or is not a coking issue, to claim I am now committed to the repair was total rubbish as they are more than capable of putting the manifold back. He did not seem to know what to say at that point. He then said he was unable to quote for the job, but only offer an estimate as the job could take up to 3 days… Again total tosh…. If there is a de-coke needed it takes 30 minutes to do (I had it done to my mini last year) not the 4 hours he said it would take and replacing the manifold would take tops 20 minutes so the maximum time is an hour. He said it was a hugely complicated job and I clearly did not know what needed to be done , which as you can imagine angered me somewhat…. After I demonstrated I knew exactly what was involved and the time it took he admitted that he need the flexibility as they were down on staff. I said I was not prepared to pay for time that was not needed and to say he needed three days was ridiculous. He then got his boss who agreed they only needed 3 hours, but I still said no you don’t and what the hell were they pulling. This is after performing a service on two occasion that was not what I booked and tried to charge me for……So I said that I wanted the car back and they tried to protest saying I could not drive it home… again clap trap as the limp home only happened once and did not do it again. The estimate came in via email and was from £1,700 - £2,200 (inc VAT) but subject to change, but the minimum being £1,700…. They also said the job would only take 3 hours but would need to have the car for 3 days due to staff shortages…..Fast forward to yesterday. I decided I was going to take the car to the BMW specialists in Turners Hill near me called BMR and the chaps that did my Mini’s cam chain. I started the car and the engine management light came on but the car seem to be behaving correctly. Got to the garage, explained what happened and what Vines said and they laughed but were not surprised. I spoke with one of the co owners and he confirmed that a compression test would immediately confirm a coking issue, but he then told me something I did not know. As the manifold issue is a known problem so the manifold had a small dipstick/nipple at the top of the manifold expressly to check if the engine had a coking issue and was a simple 5 minute job, which Vines should have checked that immediately….. They did a quick diagnostics and confirm the actuator had failed or seized and that swirl flap 4 was non longer activating correctly. Best case scenario there is no coking and actuator has failed and therefor should be replaced under warranty or worst case a de-coke and new manifold would be needed…. They would like to have the car for half a day but would charge 2 hours labour maximum as it is a “simple job”.I was then asked if I wanted to see what they did for this job as they were about to start that exact process on a 2012 520d. I obviously said yes and they showed me the coked up manifold and cylinders. It became very clear to me my car was probably suffering the same problem. So booked it in for Thursday….. As the manifold is a sealed Item and made of plastic it is impossible to clean and is an expensive part at £600 +VAT and the de-coke would be £230 +VAT all in £1,015. Vines want £690 +VAT for the manifold but a whopping £708 +VAT for the de-coke plus labour charges…. So a huge saving but still financially ruinous when you were hoping to go on holiday! Suffice to say I much prefer dealing with people who have true product knowledge and not the local village idiots that Vines seem to employ as their service advisors (who clearly do not have any product knowledge at all). So I will no longer be take my car to Vines unless it is for a warranty item as they are far to expensive and frankly I simply don't trust them.. Cheers All RC
