How much does it cost to replace timing chain on my 323i 2011
The car showed engine sign second time in the last couple of days. I went to my mechanic and he said the problem is in exhaust VANOS and the filters needs to be changed he said he will clean it if he could to save me some money he cleaned it and switched the filters, he put the exhaust one in the intake and the intake one in the exhaust. And then the check engine sign came back on and I went to him again he said the code is from the exhaust VANOS again the problem might be in the timing chain
