Volvo Forums - Volvo Enthusiasts Forum - C70 with abs,ce, brake and flashing arrow on

Hi all I am new to this forum but not new to the problems face by C70 Volvo owners.

I have a 2000 C70 Coupe LPT since 2003 it has about 105,000 miles

In 2008 I had the tcm reprogrammed through the Volvo C70 factory recall as I was having the irregular idle issue. These were additional codes that were pulled.

P0113 - Intake Air Temperature Circuit High Input
P0236 - Turbocharger Boost Sensor A Circuit Range / Performance
P0102 - Mass or Volume Air Flow Circuit Low Input
P0238 - Turbocharger Boost Sensor A Circuit High
P0014 - B Camshaft Position - Timing Over-Advanced or System Prfm Bank 1

In 2008 before the tcm reprogram, the brake light, abs light, check engine light, and flashing arrow came on intermittently with the bl, abs, and ce coming on after a few miles of driving causing the speedo to short out and than proceeded by the flashing up arrow usually when the car would come to a stop and the car would continue in 3rd or winter mode. If I turn off the engine at the stoplight the car would continue in D as normal

2 weeks ago I finally had the pnp switch replaced with a brand new unit, as suggested by this forum and others. However the lights are all back.

The only related part that has not been replaced is the abs unit, is this now the best option to replace it. Because I don't want to replace it and find out it a bad tranny after all.

Any help from the tech guys would be greatly appreciated, also for any Austin Owners is Austin Voltec a good place to surface your car I had been there a few times. Also any help with the codes would help. Thanks so much this forum is a great help to c70 owners! :)
