VANOS REPAIR question

Hi,

My m3 has vanos problems. There is a mechanic that can fix it for $2800 replacing the whole vanos system.is this a fair price? Im located in South Florida.

Any recommendations?

Use the search function my friend. There's many vanos issues out there. Is your exhaust hub tabs broken? Do you need a new solenoid?

The car is with the mechanic. I dont know exactly but will know tomorrow. What i do know is that intake retarder showed up and it'll need valve adjustments.

I am thinking of changing the whole thing by myself or should i only replace what is deficient?

Just do it all yourself. Follow beisans instructions. Buy oem parts. Its easy. Just time consuming. I didnt need an exhaust hub, nor did i do the rattle kit. I did the sprocket sleeve bolts w/med strength loctite, s62 diaphragm springs, upper chain guide, new crush washers for the bolts, besian oil pump disc, beisan seals kit, new VCG, new rubber grommets, new spark plug well gaskets. Rented timing tool. New spark plugs. Spent 500 on those parts. Plus i had to buy a used vanos unit for 300 from beisan, because during my rebuild i found my problem. The outer radial bearing ring inside my vanos unit was broken. Also i didnt get my 150 core back for the oil pump disc since it was damaged. So total ended up being 950.
Still way cheaper than 2800. Plus all my stuff is upgraded. Do it yourself man. Tell your mechanic to stop touching your car and tow it home and fix it. It took me about 16 hours from start to finish.

as mentioned earlier you really need to find out what exactly is wrong with your Vanos. some mechanics just replace the whole thing not knowing there are other fixes out there. also they can mark-up and get more labor out of you. it can be as easy as just the Vanos' solenoid. which Beisan sells rebuilt units of.
here's the info.

I had generic code p0012, intake timing over retarded. Bmw code 184, function inlet vanos. When i popped off my VC, both of my camshafts were in the retarted position. The holes in the camshafts were pointing up
