Smoking D5 - Is it worth it ?

[charliek72]

Hello, New to this but hope someone can help.

My 2005 V70 D5 (153K 5sp 163bhp) is sick ! She's recently taken up smoking and not just when you boot her. Intermittently during acceleration and during no acceleration an embarrassing haze of smoke can be seen in the rear view mirror. This in conjunction with a strangled sometimes hesitant and jerky feeling when lightly accelerating. Coasting usually fine but can still have haze being emitted. Occasionally this also means the 'Engine Service Urgent' code appears.

It took it to one chap who didn't really help so not worth stating what he did. Second seemed much more able to diagnose issues but sadly not solution other than we start with these, it might fix it, if not we keep going but the bill could be big. On that basis I decided to let the old girl go to someone who could do a better job than me trying to sort it themselves and not have to pay what could be an extensive labour bill.

However, I loved the car and had second thoughts. She still due to go under the hammer on Wednesday but felt I ought to ask others more knowledgeable than me if I should give her one last reprieve because I've not done a 'simple-ish' 'cheap-ish' fix that will keep her going for a few more K's.

I'll details what the mechanic found and hopefully someone can piece together the clues and give a second opinion.

Stored Codes :
6805 - Boost Pressure Regulation - Incorrect Flow intermittent
130C (might not be C but that's how it's written) - Mass Airflow Sensor Invalid Signal - Intermittent.

Here's the notes from the invoice. (My notes in brackets)

Investigated further.
Removed engine under tray and found exhaust bracket laying on it.
Front exhaust catalyst DPF pipe split at flexible joint (I didn't think it had a DPF but anyway)
Major Oil leaks from engine (not sure where these are coming from and it hadn't seemed to be using oil so surprised these classed as major)

So my question is - Will sorting the exhaust probably sort the smoke issue and the codes that it's causing or is there likely to be more issues than that and not worth getting into it. If it would sort how much should I expect to pay to get the exhaust sorted.

Thanks in advance for any help.

Charlie.
