Hi all. Recently bought an 04 1.9TDI AVF 130 and I have the following problem. When starting cold, its is hard to start (takes around 5 secs). At the same time I get the brake light flashing and 3 beeps from the dash as well as a bit of smoke out the exhaust. I've replaced all the filters and fitted a new battery. There's oil around the EGR, and the temp sensor was replaced by the dealer I bought it from to clear an Engine Management light. The beeps only seem to happen at the same time as the hard starting.

Can anyone advise what might be causing the beeps and hard starting? The liquid from the old fuel filter was clear yellowish in colour. I found out a few days ago it had a new camshaft, valves timing belt etc fitted by Arnold Clark earlier this year when the previous owner decided not to change the TB when the water pump was leaking...I've seen possible solutions on here that include EGR, tandem pump leak, air leak on fuel lines, incorrect timing or fuel timing, but not sure the best place to start...Any advice appreciated.
