But it the codes come back then need to re-time engine plus replace the crank hub bolt 11 21 1 439 395 and properly re-torque it. most likely got loosen when the belt got stuck in the pulley. Note: recheck bolt part number it may not be correct because no VIN # provided Good luck bud |

be careful from holes that one of them used to hold crankshaft during timing as they close to each other

RE: 2007 BMW 525i errors 2A98,2A99
And how about rings on camshafts, any wear in cylinder head where are the rings in contact with head?

RE: 2007 BMW 525i errors 2A98,2A99
Again sorry for the bad news, I hope am wrong but you have the codes:
2A98 crankshaft inlet camshaft correlation 2A99 crankshaft exhaust camshaft correlation in other words the correlation (timing) between crank and both cams is incorrect, those aren't vanos plausibility or control or adaptation that can be cured with outside parts, or the wear in the cam journals Good luck |
