BLB is a code for a 2.0TDI 140 engine. Engines with this code - usually fitted around 2005 - have a chain driven oil pump. The chain is susceptible to breaking and the resultant repair costs are wallet-damaging. There are codes other than BLB which also have this drive. I don't know what they are, though.

You can find the engine code in the; V5; service book; and, I think, the spare wheel well.

BRD, BVF, BVA, BRE, BLB, BNA, BRF and BPW, BRC

These are the codes that can be affected , only by having the sump removed and an inspection can you tell if its chain driven , but the most common to have this issue has been the BLB .

Can the sump be removed with the engine in situ?

Yes , I think A8 (Audio master tech) on here said its about a 2hour job .
