Yellow circle, with triangle and exclamation mark – The Electronic Stability Program (ESP) dashboard light flashes if the ESP or traction control is activated whilst driving. If ESP or traction control has been switched off, it will light up continuously. If ESP or traction control is not turned off and the warning light illuminates continuously, it indicates a problem and malfunction with either ESP or traction control.

So why does another fault light come up when brake pedal pressed ,Try reading the codes again with a diagnostic tester that has the relevant codes built into the machine and not a micky mouse device
I suspect bad Brake Pedal Position (BPP) switch. Check & replace if necessary the brake pedal position switch placed above pedals on the support. The best idea is to access the ABS ECU (Electronic Control Unit) using diagnostic equipment (VAS, VAG-Com, or similar) connected to the data link connector of the car, in order to pull out all DTC's (Diagnostic Trouble Code) memored. Then you will be able to replace bad pieces (e.g.: brake pedal switch, front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard. Good Luck!
Check & replace if necessary the brake pedal switch placed above pedals on the support. If the problem still occurs you might access the ABS & ESP ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored. Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ABS ECU & reset it.
The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: brake pedal switch, front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard. I'm convinced that your brake pedal switch is faulty because the glow plug warning sign went ON after ESP warning light. Just replace the brake pedal switch, see if rear stop lamps light when press the brake pedal, and test the car on the road. Good Luck!
Does the symbol look like an upside down y?
If so it is the lambda sign (the elleventh character of the greek alphabet), meaning that there is something fishy going on with the emissions part of the cars engine management.
Try to disconnect the battery over night and see if it goes away.
If not you could bring the car by the local Volvo garage and have them read fault codes and reset them for you, usually without cost.
I'm thinking that it might somehow have been triggered by the towing, and that it will go away when reset. I would therefore advice you not to do any repairs before you've tried having the codes cleared and driving around for a while to see if the light reappears.
