Cry Like A Baby 156 jtd problems

I have noticed that on my alfa 156 jtd 1.9 16v 2005 heater unit stopped working.
Does it have to do anything with air con gas? As i guess it is finished - is it worth to go refill it first and hope that heater / cold air will work then ? It takes atleast 5minutes to demist window in the morning.. Sadly i work every day and have no time to book and leave my car at the garage.. so thinking to go for a quick gas refill as soon as i have time.
Also recently i got error code i think p0238 - it says turbocharger circuit A voltage too high - got it readed after getting limp mode and engine light on.. garage quickly checked the hoses said that all seems to be ok.. what other posibilities to solve this problems are? I have checked ebay there is innotec turbo clean - cost about 50quid and cleans turbo it says and sorts limp mode- is it worth a try ? did any1 heard about it ? sadly i have no knowledge about cars and can only afford booking a day at garage next week, so would appreciate if anyone could help me out what to expect and prepare myself as without car i wont be able to get to work and driving with limp mode and heating/air con not working does my headache...
Thanks in advance for help

Hello schranz,

I would have thought your heater failure is unrelated to your aircon gas levels. More likely to be the switch on the dash, a fuse gone or the blower motor has failed. Or just possible the intake/ pollen filter is totally clogged, or (reaching for straws here) your heater matrix is clogged up.

I have used innotec turbo cleaner, it does seem to help. Wish I knew more about your particular model of Alfa, but if the turbo is electrically operated, and the variable vanes cannot move thro their full travel, that could account for the fault code showing voltage too high. The innotec treatment might well free that up. Rather than just taking her to a garage, a better bet would be finding an Alfa specialist familiar with your car.

I hope that helps you, best of luck

The Captain
