Straight6 josh Posted November 14, 2014 Report Share Posted November 14, 2014 Hi all, just recently my 330ci seems a little slower than it use to be, I noticed it a few days ago. It's mainly noticeable below 3.5-4k revs, now I know the 330 engine does sort of burst into life above 4k but it seems slower than what it should be. Now I will be replacing the DISA valve asap as it is rattling and don't fancy it finding its way through my engine, can a faulty DISA valve cause such a loss in power ? Should also mention it seems a little nippier when it's warming up, seems to get sluggish when it's up to temperature. The car has done 99k and since I bought it it's been fine, only within the past few days have I had this issue. Something I came across while looking for similar problems on other posts is the Vano seals, now I don't know if these have ever been replaced (I'm guessing they have considering it's covered 99k) is there a way to check ? Not noticed masive oil consumption like some others have, I topped it up a month ago so I'll be checking it again tomorrow to make sure. Is there any thing else I can check ? Also worth mentioning it's due its service which I will be doing when I do the DISA Any help on this is much appreciated Thanks Josh Bmw 330ci Manual 2004 Link to comment Share on other sites More sharing options...
Rob- Posted November 14, 2014 Report Share Posted November 14, 2014 First (free) thing to do is unplug the mass airflow sensor to see if it improves. Link to comment Share on other sites More sharing options...

Straight6 josh Posted November 15, 2014 Author Report Share Posted November 15, 2014 First (free) thing to do is unplug the mass airflow sensor to see if it improves. Ok, I'll unplug the connection and see if it improves, I'm guessing this resets something to factory settings ? So if it does improve is my MAF knackard ?

Straight6 josh Posted November 15, 2014 Author Report Share Posted November 15, 2014 I would also do an adaptation reset This the one where you turn the key to the first click for 10 seconds then back for 10 ? Thanks for the reply Link to comment Share on other sites More sharing options...

Straight6 josh Posted November 16, 2014 Author Report Share Posted November 16, 2014 Well iv done the adaption reset and it does seem a little better but still sluggish, so much nicer having a faster throttle response though ! Should have done it months ago ! Link to comment Share on other sites More sharing options...

Straight6 josh Posted November 17, 2014 Author Report Share Posted November 17, 2014 No joy with unplugged maf? Sorry forgot to reply, I unplugged it but it didn't seem much different odly enough, I was fitting my Coilovers this weekend and noticed my brakes front and back are binding slightly, not a lot but enough so that I'm going to strip them down and rebuild them next week ! I don't think there binding so much it would make it feel as sluggish as it does but it's probably not doing my mpg any good ! Link to comment Share on other sites More sharing options...
Straight6 josh Posted November 20, 2014 Author Report Share Posted November 20, 2014 Just an update, checked my oil level today and its low again, I last topped it up around 6-7 weeks ago up to just under the max mark in dip stick, I'm now near the minimum mark. Am i looking at failed VANO seals ? Is there I way I can check? The car doesn't seem to burn any blue smoke, and there are no signs of an oil leak.

Jay. Posted November 20, 2014 Report Share Posted November 20, 2014 i've had 5 330ci's now & 3 of them felt sluggish when i bought them.Camshaft position sensor (inlet) was duff on all 3 & wont thrrow a managment light so i'd get it INPA'd (a bmw diag software) to tell you if its duff or not.

the_driller Posted November 20, 2014 Report Share Posted November 20, 2014 They love to burn oil. I check mine monthly and probs put maybe a litre every 2000 miles or so Sent from my GT-I9500 using Tapatalk 2 Link to comment Share on other sites More sharing options...

Rh888 Posted November 20, 2014 Report Share Posted November 20, 2014 Sounds v similar to the issue I had. Thoroughly check each coil. Check the rubber boot all the way up and onto the hard plastic part of the coil. Mine had blistered only slightly causing the coil to arc on the engine block. No codes or lights. Changed all the coils. Drove like new. Worth a try! Link to comment Share on other sites More sharing options...
Straight6 josh Posted November 21, 2014 Author Report Share Posted November 21, 2014 Thanks for the replies people ! Yeah iv read all about how much oil these bmws like to drink ! With oil consumption like this would I be looking at vanos seals ? Like I meantioned earlier I don't know if they have ever been done, I'm guessing by 99k they have but have no idea when Link to comment Share on other sites More sharing options...
B0B Posted November 21, 2014 Report Share Posted November 21, 2014 It won't hurt to change your Vanos seals on that sort of mileage because unless the car was owned by a forum member or enthusiast it's doubtful they have been changed. But worn out vanos seals do not cause oil consumption. Oil consumption is usually caused by a blocked CCV, brittle cam cover gasket that's weeping, or worn valve stem oil seals or piston rings.

Thanks for the reply, iv found a good guide to doing the vanos so i will replace the seals after pay day when I will be fixing/replacing my DISA valve too. Also I think there is a DIY on this forum about sorting the CCV so I may aswell do it all at once ! Link to comment Share on other sites More sharing options...
Chimp Choker Posted November 21, 2014 Report Share Posted November 21, 2014 I'd be interested in the results on this. Been thinking of doing my CCV and vans seals Link to comment Share on other sites More sharing options...
Fuelbills Posted November 21, 2014 Report Share Posted November 21, 2014 Just for extra info I replaced my ccv valve and piping cleaned out the dipstick tube etc Used the cold climate ccv and it has made no difference to oil consumption on mine I'm lucky if does 800 miles without using over a litre it doesn't smoke really but does puff out on start up if I leave it for a few days I fact it starts misfiring probably due to the oil sat on the piston and covering the plugs it's probably knackerd valve stem seals on mine but I have not carried out a comp test yet but needs doing really as I'm getting fed up of it and need to decide weather I'm gonna bin it or waste even more money on it Link to comment Share on other sites More sharing options...
Straight6 josh Posted November 28, 2014 Author Report Share Posted November 28, 2014 Thanks for the reply, I will probably replace my CCV and the piping anyway as I doubt it's ever been done, it might even cure the issue ! Now then, has anyone in here bought one of the DISA repair kits from eBay ? They seem a good idea as replacing the whole unit is expensive and 2nd hand ones in good nic are rare. It replaced the plastic flap with a billet aluminium one and a few other bits, also removes the retaining pin and comes with new seals If anyone has used these nuts feedback would be greatly appreciated !

BmEagle Posted December 1, 2014 Report Share Posted December 1, 2014 There have been a few threads on this. Do a search on disa kits ? Link to comment Share on other sites More sharing options...
theworkerbee Posted December 1, 2014 Report Share Posted December 1, 2014 Yeah I have used it, probably didnt need to as the DISA valve was in near perfect condition, but I thought its better to be safe. Remember, if the valves vacuum isnt working correctly, or there are any cracks to the casing you will need to buy a new unit. Hope this helps.
